A retractor for oral and maxillofacial surgery

Abstract

The invention discloses a novel expander for oral and maxillofacial surgery. The expander includes a mounting plate, a fixing device is arranged on the right side face of the mounting plate, the outerside face of an arc-shaped plate of the fixing device is fixedly connected to the middle of the right side face of the mounting plate, and two symmetrical adjusting bases are arranged at the lower end of the right side face of the arc-shaped plate; the fixed ends of retractable rods of the adjusting bases are fixedly connected to the arc-shaped plate, a clamping groove is formed in the side faceof a fixing base of each adjusting base, screw rods are arranged in the clamping grooves, and the upper ends and lower ends of the side faces of the screw rods are both rotatably connected to the adjusting bases. The novel expander for the oral and maxillofacial surgery is simple in structure, adjustable and convenient to fix, the head of a patient can be fixed, the expander is prevented from being detached from the oral cavity of the patient, and the oral cavity of the patient can be expanded through L-shaped plates with supporting boards. Manpower is saved, the expansion size of the oral cavity can be adjusted through the screw rods, the operation is simple, and the expander is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractor for oral and maxillofacial surgery. Background technique [0002] Oral and maxillofacial surgery is a department that focuses on surgical treatment and studies oral organs, facial soft tissues, maxillofacial bones (maxilla, mandible, zygomatic bone, etc.), temporomandibular joint, salivary glands, and some related neck diseases. In the subject of prevention and treatment, when performing oral and maxillofacial surgery, oral retractors are usually required. The existing retractors are mainly used to hold the retractor in hand, which wastes manpower and the patient's head moves. , the spreader will be detached from the patient's mouth, which is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a spreader for oral and maxillofacial surgery, which h...
